👇🔥Well there it is. Thus far 2026 is already ranking #4 for number of hot days (defined as >34°C) as of only June 28th. Based on the current 10-day forcast this year is on track to absolutely smash all previous records. 😬😬 #wine #viticulture #climatechange
👇Waiting for my flight to California to escape the heat of France. 😂 A colleague shared this photo with me of the past heatwave damage in our VitAdapt parcel. Berry temperatures of 55°C! 😬 #climatechange #wine #viticulture
👇🔥Maybe to be expected, but through last Saturday 2026 (purple line) is tracking as the hottest year on record in Bordeaux. Look at it kick up in late May (around day 140ish) It will be going vertical during the next 10 days and the gap should become more obvious. 😬 #climatechange #wine #viticulture

👇Regarding varietal innovation and hybrids. Consider reducing humankind's experience with winegrape growing to 24 hours, and then compare with the time using hybrids or growing in tropical regions. The laters have way more potential than we realize. Learning takes time. #viticulture #wine

👇I shared Yishai Netzer's commentary about irrigation in Bordeaux; here is a response. Also very thoughtful. The two are complementary; this not really being a "rebuttal". Also I know Yishai, being from Israel, is 110% conscious of water resource issues. #irrigation #viticulture

👇A good example of expanding irrigation in EU viticulture. Here a drastic increase in Spain (y-axis is wine volume). We are working on a commentary piece with Vicente Pinilla and others and this trend has continued; production from irrigated vineyards has now surpassed rain-feed.

👇This grounded, thoughtful commentary by Yishai Netzer et al (a great researcher for whom I have a lot of respect) is actually a re-post from 2022. Here we are again. And gotta love the provocative headline; was that purposefully created to piss people off?😂 #wine #terroir

👇100% Agree. The AOC regulations are antiquated. Although established with good intent; the climate in Bordeaux is completely different today. Most producers lack the acclaim to leave the AOC making exits like this important in that they could influence positive change for the remaining producers.
Celebrated producer Lafleur leaves the Pomerol and Bordeaux appellations. What are we to make of this news? wineanorak.com/2025/08/27/w...
👇Some of this data was already shared by @wineecon.bsky.social , but the fine grain data in the article is worth checking out. It is interesting in that although yes there are differences the negative trend is universal. #wine
